PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device and an ultrasonic image generation method capable of generating a clear ultrasonic image even with respect to a direction deviated from a normal direction of an element of a probe.SOLUTION: A first reception focusing part of a tissue image generation unit 4 performs reception focusing in a normal direction of an element of a probe 1 on a reception signal obtained by a reception unit 3 to generate a sound ray signal for imaging tissue. A first detection processing part performs detection to generate an image signal for imaging tissue. A band restriction part 21 of a needle image generation unit 5 restricts the reception signal to a signal of a prescribed low frequency band. A second reception focusing part 22 performs reception focusing in a direction facing the needle to generate a sound ray signal for imaging a needle. A second detection processing part 23 performs detection to generate an image signal for imaging a needle. |
